Abnormal Shutdown
WDR has been designed to operate for long periods without malfunction or
abnormal shutdown. In case of power failure, the system will automatically reboot
when power is restored.
!
CAUTION
If admin is selected for auto log-in and power is cycled to the unit, the
person present when the system comes back up will be automatically
logged on as the administrator and have complete access to the system
(administrator’s rights). For auto log-in details see page 2-18.
However, when major parts (such as hard disk) malfunction due to external electric
shock, physical damage, or other reasons, operation of the system can become
locked up. In such situations, the internal watchdog circuit is activated in order to
reset the system for rebooting within 2 minutes. The system will then recover
normally.
In some cases, major parts (such as hard disk) are damaged to t
he extend that it is
impossible to recover normally. This will cause continuous rebooting by watchdog
or deadlock without reset. Countermeasures for abnormal discontinuation are as
follows.
1. If the power cannot be turned off by pressing the power button, turn it off by
pulli
ng the power cord.
2. Wait for 10 seconds and reconnect the power
. Ensure the system is
functioning properly.
3. Consult your local Weldex Corporation representative if system is not
functioning properly after reconnecting
power.
Automatic File Testing and Recovery
When all files in the hard disk have been closed properly during normal shutdown, it
will take only a few seconds to examine the files after rebooting.
However, when recovery is required it will take a f
ew minutes or more for
Auto-Scan and Auto-Recovery to complete necessary operations.
NOTE
Generally, when all files in the hard disk have been closed properly during
normal shutdown, it will take only a few seconds to examine the files after
rebooting. However, if file recovery is required, the process will take
additional time (a few minutes or more).
